Abstract
Official abstract text for this publication.
A control apparatus of a web processing system that executes predetermined processing onto a web continuously existing along a movement passage, in which the web processing system includes a rotating body that rotates while being in contact with the web, and the control apparatus controls a rotation speed of the rotating body such that a circumferential speed of the rotating body at a contact surface with the web matches a transport speed of the web.
First claim
Opening claim text (preview).
What is claimed is: 1. A control apparatus of a web processing system that executes predetermined processing onto a web continuously existing along a movement passage, wherein the web processing system includes a first rotating body that rotates while being in contact with the web, the control apparatus controls a rotation speed of the first rotating body such that a circumferential speed of the first rotating body at a contact surface with the web matches a transport speed of the web; and wherein a distance from a rotation center of the first rotating body to a contact surface of the web in contact with the first rotating body, changes as the first rotating body rotates. 2. A control apparatus of a web processing system that executes predetermined processing onto a web continuously existing along a movement passage, wherein the web processing system includes a first rotating body that rotates while being in contact with the web, and the control apparatus controls a rotation speed of the first rotating body such that a circumferential speed of the first rotating body at a contact surface with the web is constant; and wherein a distance from a rotation center of the first rotating body to the web in contact with the first rotating body, changes as the first rotating body rotates. 3. The control apparatus according to claim 1 , wherein the rotation speed of the first rotating body is controlled based on a change in a distance from a rotation center of the first rotating body to the web while the first rotating body rotates one revolution. 4. The control apparatus according to claim 1 , wherein the rotation speed of the first rotating body is controlled such that the rotation speed decreases as a distance from a rotation center of the first rotating body to the web increases. 5. The control apparatus according to claim 1 , wherein the web processing system includes a second rotating body that stays in contact with the first rotating body, and the control apparatus controls a rotation speed of the second rotating body such that a circumferential speed of the second rotating body at a contact surface with the first rotating body matches the transport speed of the web. 6. A control apparatus of a web processing system that executes predetermined processing onto a web continuously existing along a movement passage, wherein the web processing system includes a first rotating body that rotates while being in contact with a non-processed surface of the web, and a rotation speed of the first rotating body is controlled based on a change in a distance from a rotation center of the first rotating body to a contact surface of the web in contact with the first rotating body, while the first rotating body rotates one revolution. 7. The control apparatus according to claim 6 , wherein the rotation speed of the first rotating body is controlled such that the rotation speed decreases as a thickness of the web at a contact surface with the first rotating body increases. 8. The control apparatus according to claim 1 , wherein the first rotating body includes a manufacturing error which causes a distance from a rotation center of the first rotating body to the web not to be constant in a circumferential direction of the rotating body; and wherein the rotation speed of the first rotating body is controlled based on the manufacturing error. 9. The control apparatus according to claim 2 , wherein the first rotating body includes a manufacturing error which causes a distance from a rotation center of the first rotating body to the web not to be constant in a circumferential direction of the rotating body; and wherein the rotation speed of the first rotating body is controlled based on the manufacturing error.
